Minecraft farmer should sow and reap but how?

How can I get a farmer to plant seeds in minecraft pocket edition and harvest them again without having to do anything, please help me

So if you harvest the wheat at a village, they'll see it for themselves. But it may be that you have to wait just wait until that happens.

But I want to artificially spwanen in creative and have the put on a field and he should work but I do not know how

He can't just do that, try to give him seeds, he also has an inventory that he uses while working.

You have to give it a few seeds, they also have an inventory.

But he does not want to take the fly through it

Are you lying on the floor? Or does he take her up shortly afterwards?

I've already thrown that and then so that they are under their feet but he does not take them

Then I would not know how to do that
